Khuram Butt was based at Westminster Tube station
The terrorist was based at Westminster Tube station, with access to tunnels under the Houses of Parliament, despite having appeared in a documentary about British jihadists.
Butt, 27, was shown unfurling the black flag of Islamic State on the show called The Jihadis Next Door, screened four months before he got the customer services job at Transport for London in May 2016.
Pakistani-born Butt, who came to Britain as an asylum seeker, claimed on his CV that he carried out a range of duties including “incidents and emergencies, assisting to ensure the safety of customers and staff”.
He described himself as a “trusted individual with the drive to make a difference”.
In the document, obtained exclusively by the Daily Express, Butt also describes himself as having the “ability to work under intense pressure while managing multiple tasks” and being “a strong team player” who is “relaxed in tentative situations”.
He lasted five months in the job after reportedly being sacked for poor attendance.

But within three weeks he was working as a security guard in London.
His longest period of employment – three and a half years – was at a KFC franchise in East Ham.
However, Butt became known to MI5 in 2015 and an investigation was opened after concerns reached counter-terrorism officers.

His terror links raise more questions of how he slipped under the authorities’ radar.
The father-of-two from Barking, east London, was an associate of jailed hate preacher Anjem Choudary and a follower of his banned group Al Muhajiroun, which has been linked to a quarter of Britain’s terror offences between 1998 and 2015.
Butt was even seen with Choudary at a rally the day after Drummer Lee Rigby was murdered by fanatics.
